Which expression is equivalent to the expression below? (m+3/m^2-16)/(m^2-9/m+4)

B. 1/(m-4)(m-3)

Step-by-step explanation:

(m+3/m^2-16)/(m^2-9/m+4)

Lets factor the numerator and denominator

use identity a^2 - b^2 = (a+b)(a-b)

we have divisiion sign in  between, change the division symbol in to multiplication symbol by flipping the fraction in the denominator

(m+3/m^2-16)*(m+4/m^2-9)

Cancel put m+3  and m+4  at the top and botom

your answer would be b

the rate of change is 25
